Cal. R. 7.953
In any case in which the court orders that funds to be received by a minor or a person with a disability must be deposited in a financial institution and not disbursed without further order of the court, the order must include a provision that a certified or filed endorsed copy of the order must be delivered to a manager at the financial institution where the funds are to be deposited, and that a receipt from the financial institution must be promptly filed with the court, acknowledging receipt of both the funds deposited and the order for deposit of funds.
If, in the order approving the compromise of a minor's claim, there is a finding that the minor will attain the age of majority on a definite date, the order for deposit may require that the depository permit the withdrawal of funds by the former minor after that date, without further order of the court.
